I assumed my network was working fine, and I followed the instructions for b). Using the comparable bundles listed in the “Siemens NX Windows Requirements and Instructions” (which I will not list here for legal reasons) I was able to get NX to start successfully. I did not have to restart after adding my environment variables.

Thanks to RPI for documenting this issue. Hopefully UMD includes an update to their instructions. Otherwise, I hope that this post helps UMD students.
